Hi, we are using ODI version 11.1.1.6.0.
We want to use Smart import option from CMD prompt through import batch scripts, but could not find a command option, as like older 'OdiImportObject' for smart import feature.

I don't think this tool is there in the pallete though the facility available in odi studio. The only solution coming into my mind is to use API. Here is the package you can use
oracle.odi.impexp.smartie.

Take the help of available interface that is ISmartExportService and ISmartImportService.
Let me know if you are able to create it or else i will write few codes on it for initial understanding.
